Botletics SIM7000 LTE CAT-M1 NB-IoT Cellular + GPS + Antenna Shield Kit for Arduino (SIM7000A)

• Unlike some other Arduino shields I’ve purchased, this things works and has a robust library. The wiki does take a little bit to figure out. It’s hosted on one GitHub repo and the code is on a new one. It refers to the Adafruit library and initially I was mistakenly using that with ok results. Things got much better when I used the Botletics one though. It works great on an Uno and I’m currently using it with a Nano.
• This works and is compatible with at least arduino uno boards as well as mega. I\'m using off brand replicas and still works as intended...Main issues you may encounter:*** Make sure the solder joints on the header pins are solid. I had slightly week solder points originally, and while it worked great originally on the uno, when I swapped to the mega (for more global memory storage), the mega board headers were slightly off center enough to apparently put tension on the pins from the botletics sim to break solder joints and it could no longer communicate with the board properly.*** Need an external battery specific for the board. Make sure it\'s proper capacity, volts, as well as polarity (a lot of these battery sizes are reversed from the board polarity connector).Once those 2 main issues were taken care of, was able to successfully communicate with the board using a free hologram sim card (US for the US botletics board). Tracks GPS location great, and even gained connection quickly while indoors). Only issues I seem to be having is on hologram side where there is sometimes delays of up to hours for receiving SMS messages on the sim. Not sure what the deal was. When I was first testing the board, seemed like messages sent pretty quickly up to longest average was about a min, but seemed to slow down over time. It is not an issue with board connection, as I can manually trigger the arduino to make an http post sending gps data to web, and that is completed within seconds to simultaneously MQTT server as well as webhooks. Have to assume it\'s on hologram side with only SMS data, which is a bummer, as it was pretty cool being able to control the device with my phone, albeit, not necessary for my project. Unfortunately, do not think there really are that many other options for iot sims in the US that don\'t cost a lot for single device uses, as there really only seems to be 1 mobile carrier that supports these... att/tmboile.
• I am working on a project with a client, using a Hologram SIM and the provided arduino files and modified library files from Adafruit from the boards developer. I bought all versions 7000E, 7000E, 7000A with the last being 7000A. I am located in Florida, USA. I learned after working with the E and G version that the A stands for America. Both the G and E did not work where I live, the E was not responsive, the G would connect to the network but not function, the A worked beautifully! If you are in the US you NEED the 7000A chip not the others. Hope this helps save time on your end. Also, this bit of code helped speed up finding a signal. Use this with your code, this came from the LTE demo I was working with:// Configure a GPRS APN, username, and password. // You might need to do this to access your network\'s GPRS/data // network. Contact your provider for the exact APN, username, // and password values. Username and password are optional and // can be removed, but APN is required. //fona.setNetworkSettings(F(\"your APN\"), F(\"your username\"), F(\"your password\")); //fona.setNetworkSettings(F(\"m2m.com.attz\")); // For AT&T IoT SIM card //fona.setNetworkSettings(F(\"telstra.internet\")); // For Telstra (Australia) SIM card - CAT-M1 (Band 28) fona.setNetworkSettings(F(\"hologram\")); // For Hologram SIM card // Optionally configure HTTP gets to follow redirects over SSL. // Default is not to follow SSL redirects, however if you uncomment // the following line then redirects over SSL will be followed. //fona.setHTTPSRedirect(true); // Other examples of some things you can set: fona.setPreferredMode(38); // Use LTE only, not 2G fona.setPreferredLTEMode(1); // Use LTE CAT-M only, not NB-IoT fona.setOperatingBand(\"CAT-M\", 12); // AT&T uses band 12 fona.openWirelessConnection(true);// fona.setOperatingBand(\"CAT-M\", 13); // Verizon uses band 13 // fona.enableRTC(true);
• Although the Verizon website lists the SIM7000A as a modem that can be used on their network, when I tried to get a Cat-M1 SIM card from Verizon for the Botletics SIM7000 LTE CAT-M1 NB-IoT, their \"Solutions Architect\" could not add the IMEI to a SIM card because this board has not gone through Verizon\'s QA process, apparently.I\'m waiting on a SIM card from Hologram.
• I\'ll admit, the learning curve is pretty steep, but this board works great. I paired it with an old Duemilanove board (which apparently is missing the SDA and SCL pins) and got it to work with one of the example LTE demo sketches right away using the free pilot SIM card from Hologram. To get it to work with Adafruit IO, I actually had to step up the processor to a SAMD chip (I have an Adafruit Feather M0 for the job), since the 328 chip only has 32KB of memory and the sketch pushed past that limit. Arduino UNO boards apparently have a slimmer bootloader than my old Duemilanove, so it should work on an UNO. There are example sketches with SAMD boards.HTTP GET/POST works fine and MQTT works like a champ. The LTE antenna has worked everywhere I\'ve tried it. The GPS antenna is pretty weak and only seems to work outdoors. An active antenna would be a good upgrade if you need better GPS functionality.Overall, this board has exactly what I wanted for my project. LTE, GPS, and a temperature sensor.
